I own a Canon EOS Rebel K2 film camera that came with a kit lens Canon EF 28-90 mm. I am thinking of going digital and am going to buy a EOS Rebel XSi. My question is if my old lens would work on the new camera so I could just buy the body and switch it out. I eventually, in the very far future, want to buy nicer lens, but can't really afford it right now. Do they work very differently? I am not very knowledgeable on this subject. As a side note does anyone know how good the EF-S 18-55IS lens is? Should I buy the XSi as a kit or buy a separate/better lens?
Answer
The EF 28-90 will work just fine on an XSi. In fact the XSi can use all EF and EFs lenses. The 28-90 will perform differently on the XSi though. The Canon Rebels and the 40D and 50D all use an APS-C sized sensor which is smaller than 35mm film. This means that the image appears more magnified than on your film camera. You will often here this referred to as the crop factor. The crop factor is 1.6. So what you need to do is multiply the focal length of your lens by 1.6 to get the equivalent focal length on your film camera. Your 28-90mm lens will perform as a 44.8-144mm lens would on your film camera. This is good on the telephoto end but bad on the wide angle end. This is why the kit lens for the digital cameras is 18-55mm instead of 28-90mm. If you will miss the wide angle I would suggest getting the 18-55mm lens kit.
One other thing. The EFs lenses will not work on your film camera or a full frame digital like the 5D MKII. Just keep that in mind when you are lens shopping in the future.

I'm looking for a replacement lens for my Canon Rebel XSi...?
wenggay
because I broke the 18-55mm lens that came with the kit. I didn't want to get the exact lens for replacement but i don't know which one to get. I'm now looking at Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens but i don't know if it could be a direct replacement... could i actually have it directly attached to just the body of the camera or does it require a working standard zoom lens that i had? Please help me. Thank you in advance
Answer
You can use ALL...Canon EF and EF-S lenses (plus third party lenses with Canon mount) on your Rebel XSi.
I agree with Hondo. The EF 75-300mm lens is a crap lens. But what would you expect from a telephoto lens that costs a mere US$138 (from Amazon)? Lens choice is very important...and often you DO get what you pay for. Choose wisely (yes, it may cost a bit) and it will become an investment that will last for years...because spending money on a crap lens is a complete waste of money if it's not going to deliver good results.
So, you'll need to spend more than a measly $140 on a telephoto lens if you want sharp image quality. I recommend you buy a new lens with a similar focal range than your kit lens, because it makes a good general purpose lens, whereas a lens starting at 75mm, is not so 'general purpose'.
I recommend the new Canon EF-S 15-85mm f/3.5-5.6 IS USM. This lens has an ultrasonic motor and is a big step up in image and build quality than the standard kit lens. That's why it costs around US$699.

If you prefer a telephoto lens, I recommend the excellent Canon EF 70-200mm f/4L USM (US $636)

However, if it's way too much for your budget...I recommend the Canon EF-S 55-250mm (US$200-250).

If you need much better low light shooting capability, look at getting a prime lens (single focal length) like the Canon EF 50mm f/1.8 II (US $100-120) or the f/1.4 version with USM (US$345). These lenses are great for shooting handheld in low light and also portraits.
